Dave,

How is premix not adding oil to the fuel when the throttle is closed?

My understanding with premix (and yes, I do run it on all my race bikes 50, 100, and 250 cc's) is that if the engine is getting fuel, then it's getting oil. If for some reason the engine isn't getting fuel, then, well, it's probably not running.

The injector system is great, and I use it on my street bike. It's worked flawlessly for the four + years I have owned the street bike. However for racee use, I do prefer the weight savings, as well as the peice of mind that something else mechanical (and electrical) won't just go out on my while I am at full tilt in a corner.

That's just my opinion, and I'm not saying a race bike needs to run premix, just that I do, and why I do.

Also, I get to use Castrol A747 oil, and nothing smells better then race gas, and A747 :)

Thanks,
